Inverted Papilloma is a benign neoplasm originating from the Schneiderian membrane of the nose and paranasal sinus cavities. It has varied clinical and histological features involving the lateral nasal wall, septum, ethmoids, maxillary and sphenoid sinuses and at times involves the skull base. Three interesting cases are reported below because of varied presentation of inverted papilloma.

• Microlaryngoscopy and Endolaryngeal Surgery
• Neck Masses – Evaluation
• Carcinoma Ethmoid – Surgical Management

Since Inverted Papilloma is associated with chronic sinusitis, patients always had nasal and sinus surgery. Most authorities will consider this a true neoplasm because of its transformation into carcinoma as transitional cell, papilloma or squamous papillary epithelioma. Early clinical diagnosis and thorough evaluation by biochemical tests, high resolution coronal CT scanning and radical surgery is advocated. For its recurrence and malignant transformation few authorities advocate deep X–ray therapy following radical surgery. Sixteen cases were seen during 1980 to 1995 at KEM Hospital, Pune.
